چکیده

In this paper we analyze the recently proposed light-weight block cipher PRINTCipher. Applying algebraic methods and SAT-solving we are able to break 8 rounds of PRINTCipher-48 with only 2 known plaintexts and 9 rounds under some additional assumptions. We show that it is possible to break the full 48-round cipher by assuming a moderate leakage of internal state bits or even just Hamming weights. Such a simulation side-channel attack has practical complexity. We investigate applicability of our method to cryptanalysis of the full PRINTCipher-48.

Differential Cryptanalysis of Round-Reduced PRINTcipher: Computing Roots of Permutations

At CHES 2010, the new block cipher PRINTcipher was presented. In addition to using an xor round key as is common practice for round-based block ciphers, PRINTcipher also uses key-dependent permutations. While this seems to make differential cryptanalysis difficult due to the unknown bit permutations, we show in this paper that this is not the case. We present two differential attacks that succe...

Impossible Differential Cryptanalysis of Reduced-Round Midori64 Block Cipher (Extended Version)

Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differ- ential cryptanalysis, we analyze security of a family of lightweight block ciphers, named Midori, that are designed considering low energy consumption. Midori state size can be either 64 bits for Midori64 or 128 bits for Midori128; however, both vers...

Impossible Differential Cryptanalysis on Deoxys-BC-256

Deoxys is a final-round candidate of the CAESAR competition. Deoxys is built upon an internal tweakable block cipher Deoxys-BC, where in addition to the plaintext and key, it takes an extra non-secret input called a tweak. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block cipher. First, we find a 4.5-round...

Linear Cryptanalysis of PRINTcipher - Trails and Samples Everywhere

PRINTcipher is a recent lightweight block cipher designed by Knudsen et al. Some noteworthy characteristics are a burnt-in key, a key-dependent permutation layer and identical round keys. Independent work on PRINTcipher has identified weak key classes that allow for a key recovery — the obvious countermeasure is to avoid these weak keys at the cost of a small loss of key entropy. This paper ide...

A Cryptanalysis of PRINTcipher: The Invariant Subspace Attack

At CHES 2010, the new block cipher PRINTcipher was presented as a light-weight encryption solution for printable circuits [15]. The best attack to date is a differential attack [1] that breaks less than half of the rounds. In this paper, we will present a new attack called invariant subspace attack that breaks the full cipher for a significant fraction of its keys. This attack can be seen as a ...
